The Fourier Decomposition method is established as a non-invasive method for perfusion related information in the lung, and has shown promise in clinical studies. One drawback is the lack of meaningful quantification, making follow-up and comparison of patients difficult. We show that quantification of Fourier Decomposition maps is both possible and easy, requiring only a small amount of post-processing.
